The MIM-46 “Mauler” is an American self-propelled anti-aircraft missile system designed by General Dynamics in the late 1950s for the US Army. It is intended to combat low-flying high-performance tactical fighters and short-range ballistic missiles. The system consists of an M113 chassis, carrying nine MIM-46 "Mauler" (Missile) in launch canisters, a tracking and illumination continuous wave radar, and a fire control system. The system is supposed to be highly automated and capable of engaging multiple targets simultaneously, though this part seems to have a host of reliability issues. Because of this, the MIM-46 project has been partially sidelined, though some prototypes of these vehicles have been spotted in Vietnam.
